To all whom; it may oorwcm:

Be it loio'wn that l, Trrorras A... KENNEDY, of the city of Toronto, in the county of York, Province of Gntario, Cenoda, a Suhject oimthe King of Great Britain, have inimprove ments in 'Windshield Cleaners for Vehicles, of which the following is a specification.

This invention relates to windshield clean ers of the reciprocating type, and my object is to devise an electrically operated cleaner, which may be operated with a minimum or power and which may he built into the windshield "frame in such a manner as to hide all working parts except the motor.

I attain my obyect by means of the constr'uctions hereinafter described and illus- ."vided with ahead 10 adapted to trated in the accompanying drawings in Which- Fig. 1 is a recr elevation of a windshield showing my improved cleaner in position;

Fig. 2 o side elevation of the same;

Fig. 3 a longitudinel section of the same, palitly broken away, and on an enlarged sea e; r

Fig. 4 a section on the line H in Fig. 3, parts being shown in elevation; and

Fig. 5 a section on the line 5-5 in Fig. 3.

In the drawings like numerals of reference indicate corresponding-parts in the different figures. I

1 is the top frame section of a Windshield, this being formed as a U-shaped trough hav ing the open side uppermost and. its bottom formed with a groove 2 to receive the ed 8.

of the glass panel of 'she Windshield. 11

each end of this trough is fixed a block 3, these blocks being brazed, soldered or otherwise secured in osition to form oil tight joints with the hottom and sides of the trough. In each block is formed s. recess 4 forming-hearings for the ends of the shaft 5. These bearing recesses, it will he noted do not extend entirely through the blocks. lhe shaft 5 has right and left hand threeds 6 formed therein, these threads being joined at their ends by the loops 7.. Mounted to slide on the shaft is a. traveller 8, which is pre vented from turning on the shaft by its engagement with the sides of the trough.

Mounted in this traveller is a pin 9 proengage in the threads 6. This pin should be of snbstanti ally the width of the thread grooves and lightly longer so that it will properly pass the points Where the threads intersect,

while it must he capable of travelling round the loops 7. in the preferred form a threaded hole is formed in the traveller into which is screwed a threaded bushing ll which forms a bearing for the pin -9. The pin may thus he introduced from the top of the block end the bushing screwed down into position. Secured to the top of the traveller is e scraper connection 1?. which extends for- Wardly end downwardly. The lower. art of. this connection at least is prelerehlyrormed understood. A drivev shaft 15 is iournalled in the hloclc d shove the shaft 5. This drive shaft has a Worm 16 out therein adapted to engage the gear 1'? out'in the shaft; 5. The gear and the Worm being cut he'lowthe peripheries of the respective shafts, the latter are easily pushed into position in their been. ings in the block and the Worm engaged with the gear.

Where the shaftextcnds through the side:

of the trough, a. felt oil wosher'lS is preferably secured in position hy'means of o suit ahle collar. While my means may. he employedof driving; the shaft 15, I shower: electric motor 19 directly connected thereto, this motor being mounted on a hra lret -hfi secured to the Windshield frame.

' The bottom of the trough will oonteio oil, so that the shaft 5 runs in as. oil hath, snfiicicnt oil passing into hearing recesses 4. for the luhricatioh of shaft ends end for the lubrication of the Worm ill, gear 1? and shaft 15.

In order to properly luhrioate the ruhhin surfaces of the traveller 8 and trough l, provide the sides of the hloch: "with the clined grooves 21 up which the oil tehds to flow as the traveller is moved in one direction or the other. v

In order to exclude dust and dirt, I secure a. cover 22 to the rearward sideo'f the trough, which cover extends forwardly and then downsvardl in front of the trough first leaving sullihient room for she passage of the scraperconneetion l2.

It will he found that e core-p01" constructed substantially as described will vided with a pin engaging the thread of the 'shaft; a connection-fora scraper secured to the top of said traveller and extending forshaft, a worm on said a scraper mounted on said connection; adriving sha t extending through one side of the trough and into one of the end blocks above the traveller driving shaft; and a, gear on the traveller shaft with which the worm meshes. 2. In a windshield cleaner, the combination of a frame member formed as a U- shaped trough; a block at each end of the trough sealing said ends and adapting the trough to contain a bath of oil; a shaft formed as with a right and left hahd thread journaled in said blocks adjacent the bottom of the trough; a traveller mounted on the shaft to slide in said troughand proided with a pin engaging the thread of the shaft; a connection for a scraper secured tothe top of said travellerand extending forwardly and downwardly; a scraper mounted on said connection; a driving shaft extending through one side of the-trough and into one of the end blocks above the 40 traveller shaft, a worm on said driving shaft;

a gear on the traveller shaft with which the worm meshes; and a cover secured to one side of the trough, a slot being left between the cover and the adjacent side of the trough for the passage of the scraper connection.

3. In a windshield cleaner, the c01nbination of a frame member formed as a U- shaped trough; a block at each end of the trough sealing said ends and adapting the trough to contain a bath of oil; a shaft formed as with a right and left hand thread journalled in said blocks adjacent the bottom of the trough; a traveller mounted on the shaft to slide in said trough, having inclined oil grooves formed in its trough engaging sides, and provided with a pin engaging the thread of the shaft; a connection for a scraper secured to the top of said traveller and extending forwardly and down- 80 wardly; a scraper mounted on said connection; a driving shaft extending through one side of the trough and into one of the end blocks above the traveller shaft; a worm on said driving shaft; and a gear on the traveller shaft with which the worm meshes.
